10 Best Mini Split Ac Unit For Semi Truck 2026 in the United States

The Aspligo 12V Truck Air Conditioner is a mini-split system designed for semi-trucks and similar vehicles like RVs, excavators, and buses. It offers a cooling capacity of 7200 BTU, which is effective for keeping the cabin comfortable in warm conditions. The unit runs on 12 volts, making it compatible with typical vehicle electrical systems. Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features. This unit is a practical choice for truck drivers or operators seeking reliable cooling with straightforward installation, provided refrigerant charging is appropriately managed.

The Cooligo Truck Cab Air Conditioner is designed specifically for semi-trucks, RVs, and other large vehicles needing a 12V cooling solution. With a solid cooling capacity of 12,000 BTU and a strong airflow of 265 CFM, it can effectively cool areas up to 430 square feet, making it suitable for truck cabins and small living spaces. The rotary scroll compressor enhances energy efficiency and keeps noise levels low, which is important for comfortable use during long drives or rest periods. Installation as a split system requires removing an existing skylight, so some effort and proper sizing are necessary, but the system is compact and uses durable materials suitable for vehicle environments. The remote control adds convenience, allowing you to adjust settings easily.

The product claims high efficiency and fuel savings by running off a 12V power source, helping cut costs compared to traditional AC units. It also continues cooling even when the engine is off, which is a valuable feature for truckers needing rest without idling the engine. Buyers should be aware that this unit requires an outdoor component and professional installation may be needed to ensure proper setup. The limited warranty and positive customer reviews suggest reliability, but the product's weight (nearly 60 pounds) means installation might not be a quick DIY job for everyone. This AC unit represents a practical choice for semi-truck owners looking for a dedicated, energy-conscious cooling system with good power and quiet operation.

This 12V DC mini-split air conditioner offers a solid 9000 BTU cooling capacity, which is a good fit for semi-trucks, RVs, and other heavy vehicles needing reliable cooling while parked or on the road. It runs directly off the vehicle’s 12V battery without requiring the engine to be on, helping reduce fuel use and pollution during breaks. The scroll compressor provides efficient and steady cooling performance. Noise is kept low at around 35 decibels, meaning it operates quietly enough not to disturb rest or communication inside the cab.

The unit supports split system installation, which typically means better airflow and easier maintenance compared to window units, but installation may require professional help. A remote control and panel buttons allow easy adjustment of temperature and fan speeds, adding convenience on the go. The unit also has rapid cooling and a 5-level airflow system with 360° rotating outlets for even temperature distribution. On the downside, its energy efficiency rating is modest at 2 stars and a SEER of 13, so it may draw relatively more power compared to higher-efficiency models. It demands a strong vehicle battery—over 200AH—to handle the 60-70 amps current draw, which is important for users to consider to avoid battery drain.

This air conditioner is practical and convenient for truck drivers or RV owners who want a quiet, effective cooling solution powered by their vehicle battery, but it requires attention to power supply and possibly professional installation.
